摘　　要：目的:为实现防弹靶板的轻量化和高防护性,对碳化硼陶瓷/超高分子量聚乙烯(ultra-high molecular weight polyethylene,UHMWPE)纤维复合靶板的防弹性能进行仿真优化与实弹验证。方法:首先,基于ANSYS/LS-DYNA建立碳化硼陶瓷/UHMWPE纤维复合靶板的有限元模型。其次,对子弹侵彻不同厚度搭配的防弹靶板过程进行仿真,分析防弹靶板对100 m处56式7.62 mm普通枪弹的防护效果。最后,基于仿真结果,以靶板的防护性和质量作为主要指标,对靶板进行优化设计,并通过实弹射击验证设计靶板的防弹性能。结果:仿真结果表明,不同厚度搭配的防弹靶板都可以实现对100 m处56式7.62 mm普通枪弹的有效防护;实弹验证结果表明,仿真结果准确,设计的防弹靶板具有较好的防护性。结论:对碳化硼陶瓷和UHMWPE纤维设置合理的配比可以满足防弹靶板的高防护性和轻量化需求,该研究可为轻质、高防护性防弹靶板的研发提供参考。Objective To carry out simulation optimization and live-fire verification of the bulletproof performance of the boron carbide ceramic/ultra-high molecular weight polyethylene(UHMWPE)fiber composite target board in order to improve bulletproof target boards in light weight and high protection.Methods Firstly,a finite element model of the boron carbide ceramic/UHMWPE fiber composite target board was established based on ANSYS/LS-DYNA.Secondly,the simulation of bullet penetration through different thicknesses of the bulletproof target boards was performed to analyze the protection effect of the bulletproof target board against Type 567.62 mm ordinary bullets at a distance of 100 m.Finally,based on the simulation results the target board was optimized by taking the protection effect and quality of the target plate as the main indexes,and the bulletproof performance of the designed target board was verified by live firing.Results The simulation results showed that different thicknesses of bulletproof target boards could achieve effective protection against Type 567.62 mm ordinary bullets at a distance of 100 m;the live-fire experiment confirmed the result of the simulation experiment,and indicated that the optimized bulletproof target board was gifted with high protection.Conclusion Rational proportioning of boron carbide ceramic and UHMWPE fiber contributes to meeting the requirements of the bulletproof target board for light weight and high protection,and references are provided for the development of lightweight highly-protective bulletproof target board.
